vue2中computed中无法获取到this

如果你非要在computed中访问this,可以通过下面这个hack,可以用个flag来判断

data() {
  return {
    isMounted: false,
  }
}
computed: {
  nameAndPhone() {
    if (!this.isMounted) return
    const {
      reservationName,
      reservationPhone
    } = this.$refs.appointment.getFormValue()
    return reservationPhone
    ? reservationName + '/' + reservationPhone
    : reservationName
  }
},
mounted() {
  this.isMounted = true
},
